CALK-FASTENER.

Specification of Letters Patent.

Patented Oct. 18, 1921.

To all whom it may concern.

Be it known that I, DANIEL BALLENGER, a citizen of the United States, residing at Greeley, in the county of lVeld, State of Colorado, have invented certain new and useful Improvements in Calk-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and i use the same.

This invention relates to farriery, and more especially to detachable calks; and the object of the same is to improve the means for fastening the calks in place by crosspins.

The invention contemplates the insertion of two elements, herein called screw-eyes, into the toe of the shoe and one each into its heels, and the attachment of the calks to said elements in such manner that the calks may be removed to be sharpened or repaired or when they have to be replaced.

Details of the preferred manner of carrying out the invention are set forth below and shown in the drawings wherein is shown a perspective view of a shoe equipped with these calks one of the heel calks and its pin being slightly removed.

The shoe S is one of ordinary construction. In it are bored four upright holes, two of them through its toe and one each through its heels, and into each hole is seated the shank l of an element herein called a screw-eye because said shank may be threaded and screwed into this hole, although it is possible to drive the shank into the hole and upset or rivet its upper end or in some convenient manner fasten it therein so that it will not become lost or loose. The eye end 2 of this element stands below the shoe, the openings through the two eyes in the toe of the shoe being alined, and all eyes stand along parallel longitudinal planes. Each calk has an upright body 3 whose lower edge f is sharpened and tempered, and it has a base 5 at the upper end of its body whose upper face projects substantially at right angles to said body, while the lower face of the base is transversely grooved as at 6. Cut through the base from its outer edge toward the body is a notch 7 of sufficient width to receive the eye 2, the body itself being possibly channeled as at 8;

When the bifurcated or forked body is placed astride the eye the opening in the latter alines with the grooves 6, and a pin 9 is now passed into one groove, through the eye, and into the other groovethis pin being preferably tapered or wedge-shaped so that it must be driven into place to hold the parts connected. By this means an ordinary horseshoe can be readily provided with calks whose wear edges 4 may have any desired pattern.

lVhen the calks become dull, the pins are driven out and the calks removed and sharpened, as by filing, grinding, or heating and then tempering their edges; and thereafter they are reapplied in the man ner already described. At the end of the season, when calks are no longer necessary, they are all removed and the shanks of the eye-bolts driven out of the holes in the shoe. This latter may require the removal of the shoe from the hoof, whereas it is obvious that the removal and replacement of the calks will not.

lVhat is claimed is:

1. The herein-described horseshoe having a calk fastener comprising a screw-eye having its shank inserted in the horseshoe and its eye projecting below said shoe, a calk having a base at right angles to its body and bifurcated to pass astride said eye, the arms of said bifurcation being grooved in their lower faces, and a pin fitted through said eye and with its ends lying in said grooves.

2. The herein-described horseshoe having a calk fastener comprising a screweye ha.v-

ing its shank inserted in the horseshoe and its eye projecting below said shoe, a calk having a base at right angles to its body and bifurcated to pass astride said eye, the arms of said bifurcation being grooved in their lower faces and the body of the calk being channeled between said arms to admit the eye and permit its opening to aline with said grooves, and a fastening pin whose midlength stands in said opening and whose ends lie in said grooves.

In testimony whereof, I affix my signature, in the presence of two Witnesses.
